Matt,

thanks for the idea.  Our server is in an air-conditioned room, so those
values do seem realistic.

Would the 100x difference be scaled in the /etc/sensors.conf file?

Also, why would some of the cores not be connected or registering a
temperature (the temps 1-3 above)?  Is there a way to "turn on" these
readings?

Matthew.
